SYDNEY — “The Blair Witch Project” thesp Joshua Leonard is about to be terrified in Australian thriller “Cubbyhouse,” his first chiller genre role since playing Josh in Artisan’s $250 million-grossing hit.

Pic, which starts filming next week in Queensland, has an American family moving to Australia’s Gold Coast, where their children’s playhouse is possessed by a demonic presence.

Directed by Murray Fahey (“Dags”), “Cubbyhouse” is backed by the Australian Film Finance Corp., Showtime Australia and sales agent-distributor Beyond, which has already sold the film across Asia and plans a wide Oz release in June.

Since “Blair Witch Project,” Leonard has starred opposite Robert De Niro in George Tillman Jr.’s “Navy Divers” and Matt Dillon in the Martin Scorsese-produced “Deuces Wild.”
